Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

The authors analyzed retrospectively the 19 patients with mucoepidermoid carcinoma of salivary glands who were treated at Department of Oral and Maxillofacial Surgery, Pusan National University Hospital from June, 1986 to September, 1998. The results obtained were as follows : 1. There were 4 males(21%) and 15 females(79%). Age distribution was wide and the mean age was 45.2. 2. Of all mucoepidermoid carcinomas of salivary gonads, 4 cases arose in the major salivary glands and 15 cases in the minor salivary glands. The incidence according to the anatomic primary site for minor salivary glands was 8 cases in the palate, 2 cases each arising in the tongue and floor of mouth and 1 case each arising in the mandible, buccal mucosa and the lower lip. 3. In histopathological classfication of mucoepidermoid carcinoma, 5 cases were low grade. 9 cases, intermediate grade and 5 cases, high grade. 4. Perineural invasion was observed 40% (2/5) in high grade and 22% (2/9) in the intermediate grade of mucoepidermoid carcinoma. 5. The incidence of cervical lymph node metastasis according to histopathologic grade was 40% (2/5) in high grade and 11%(1/9) in intermediate grade of mucoepidermoid carcinoma. 6. The lung was the commonest site for metastasis comprising 3 cases among 3 cases of distant spread of which 2 cases in high grade and 1 case in intermediate grade of mucoepidermoid carcinoma.

Velopharyngeal adequacy is the ability of speech mechanism to create a seal between the oral and the nasal cavities during speech. The basic components of the velopharyngeal mechanism are the soft palate, the lateral pharyngeal wall, the posterior pharyngeal wall, associated musculature of the soft palate and pharyngeal wall, and the adenoid mass. If velopharyngeal inadequacy exists, the complete seal cannot be obtained during speech, resulting in hypernasal speech quality. This report is the clinical and cephalometric study of 16 consecutive cases of velopharyngeal inadequacy which were corrected by superiorly based pharyngeal flaps with lateral port control. The summarized results were as follows; 1.The total number of patients was 16(11 males, 5 females). They all showed hypernasality and nasal emission at preoperative period. 2.Hypernasality and nasal emission were shown in 13 and 5 patients respectively at immediate after operation, and decreased as 4 and 2 respectively at 6 months after operation. 3.Most patients showed snoring after operation and slowly decreased during follow-up periods. 4.During follow-up periods, the pharyngeal flap was slightly elongated at its horizontal length and moved inferiorly at its attached base. But this change was not as significant as it influenced on the clinical results.

Purpose : This study is conducted to evaluate the clinical success of secondary alveolar bone grafting using autogenous iliac particulate cancellous bone marrow in cleft maxilla. Materials and methods : We evaluated 107 cleft patients who had been admitted to the Dept. of Oral and Maxillofacial Surgery of Pusan National University Hospital from January 1, 1991 to January 31, 1999 and had been performed secondary alveola bone grafting with autogenous particulated cancellous bone marrow from iliac crest. Results : 1. Men were 70 and women were 37, which shows 65.4% and 34.6% and the proportion of males to females was 1.9: 1. Unilateral cases were 89(83.2%) and bilateral cases were 18(16.8%). 2, Age of bone grafting is widely distributed from 7 to 29, and the average was 13.2. 3. Success rate was 97.8% in unilateral cases, 94.4% in bilateral cases. Overall success rate was 96.7%. 4. We evaluated the bone graft contour by the percentage of bone attachment level adjacent to the alveolar cleft and the menial side showed 82.4% and the distal 87.7%. 5. The amount of notching the alveolar ridge at the grafted site through the ratio of notching length up to the most apical base to the length of proximal segment anatomic root was 0.19.

Purpose : The purpose of the present study was to evaluate postoperative stability and soft-tissue osseous relations of the long face syndrome patients. Methods : Twenty-five patients who had undergone bimaxillary surgery to correct long face syndrome at the Pusan National University Hospital were evaluated. The lateral cephalograms of preoperative, 1 week postoperative and at least 1 year postoperative were examined. Results : 1. The facial height of the long face syndrome patients were longer than normal Korean adults. 2. The most common malocclusion type of the long face syndrome patients in Korea was class Ⅲ. 3. Horizontal postoperative skeletal relapses were -0.64∼0.80mm in the maxilla, and -0.56∼0.48mm in the mandible. 4. Vertical postoperative skeletal relapses were 0.20∼0.56mm in the maxilla, and -0.80∼0.20mm in the mandible. 5. Postoperative soft tissue changes in long face syndrome patients were correlated with postoperative skeletal changes. So prediction schemes for postoperative soft-tissue changes were obtainable. Conclusion : It is hard to predict the exact direction and quantity of the postoperative skeletal relapse in long face syndrome patient's orthognathic surgery because of large standard deviation. But soft tissue change is predictable via prediction scheme.

The prognosis of oral malignant melanoma is poor compared with cutaneous melanoma. It may be related to the difficulty of wide enough resection, the early hematogenous matastases, higher stage at initial diagnosis, tendency to growth vertically. In the view of histological differences between oral mucosa and skin, it is impossible use Clark’s and Breslow’s classifications for prognosis. The great problem is that there is still no consensus on the treatment due to rarity. Because data collection from case reports is considered to be the best source of information and should be pooled to anlalyze key determinants of outcome, We reported on 6 cases of primary malignant melanoma of the oral cavity which were diagnosed and treated in Pusan National University Hospital recently and reviewed the literature. Immunohistochemical study on S100 Protein, GP 100 (HMB-45) with biopsy was usable to confirm the melanoma. Neck dissection including wide excision is recommended if lymph node involvement is suspected. Additionally, adjuvant chemotherapy could be supporting therapy.

The celvical flap, comprising skin, fascia, and platysma muscle, has significant application in the head and neck region after radical ablative surgery for cancer of the oral cavity. The flap may be used for recon-struction of the cheek, floor of the mouth, and lateral side of the tongue. This flap minimizes donor morbidity by use of cervical operation wound and flap size available is adequate for most oral defects and the procedure is relatively simple and time-saving. However the flap is not applicable in patients where there are large tissue defects and metastasis is suspected. We have used the celvical flap for its rapid, simple, and effective closure of oral defects after cancer ablation and found it is very useful for the reconstruction of relatively small oral defects.

Alveolar bone grafting is an essential component of successful surgical rehabilitation in many common cleft deformities. Primary alveolar bone grafting is defined as alveolar bone grafting which takes place before eruption of the primary dentition or before 1 years of age. The major objective in primary alveolar bone grafting is to prevent significant maxillary segmental collapse and arch disturbances. If severe, this can make secondary rehabilitation difficult, costly, and protracted. Such early stabilization may eliminate or, at least, decrease the amount of orthodontic arch expansion required during the transitional dentition period. Furthermore, early obliteration of alveolus fistulae improves speech and dental hygiene. It is critical that abutting maxillary segmental alignment be achieved(generally when the patient is 8 to 10 months of age) before grafting. Otherwise, the amount of dissection necessary to develop mucosal flaps for bone graft coverage will be more extensive, thus risking increased scar formation with potential adverse effects on growth. We report a preliminary result of 4 cases of primary alveolar bone graft using rib bone, performed by limited dissection and onlay graft technique at 8 to 10 months of age. They showed satisfactory clinical results especially in terms of growth up to now.
